Description
Technical field
The utility model relates to extractor tool technical fields, and in particular to a kind of liquid storage device for Solid Phase Extraction.
Background technique
A kind of Sample Pretreatment Technique Used of Solid Phase Extraction, is combined and is developed by liquid-solid extraction and column liquid chromatographic technology,
It is mainly used for the separation, purifying and concentration of sample.Solid phase extraction techniques improve analyte compared to traditional liquid-liquid extraction method
The rate of recovery, more effectively analyte is separated with interfering component, reduce sample pretreatment process, it is easy to operate, time saving, save
Power is widely applied to operation common in the fields such as medicine, food, environment, commodity inspection, chemical industry and laboratory.
In laboratory, the most volume of Solid Phase Extraction is larger, and large volume Solid Phase Extraction is typically chosen repeatedly to be repeated on a small quantity,
Not only need experimenter loading, repetitive operation repeatedly, cause to test it is time-consuming and laborious, when extraction raw material flow rate control difficulty also compared with
Greatly.In addition, raw material long-time exposed to air, labile element are easily decomposed, experimental result is influenced.
Utility model content
The utility model provides a kind of Solid Phase Extraction precisely in order to avoid above-mentioned existing deficiencies in the technology
Liquid storage device.
The present invention adopts the following technical scheme that in order to solve the technical problem：A kind of Solid Phase Extraction liquid storage device, bottle cap are set to liquid storage
Bottle bottle mouth position, is tightly connected with the liquid storage bottle, constitutes closed containing cavity, stores extraction feed liquid in the cavity；Air inlet pipe
It is each passed through the bottle cap setting with outlet tube, the air inlet pipe and the outlet tube and the bottle cap junction seal；It is described
Air inlet pipe one end is connect with the gas source, and the other end is located in the liquid storage bottle, and be located at the extraction feed liquid levels with
On；Described outlet tube one end is connect by the extraction connector with solid phase extraction column, and the other end is located in the liquid storage bottle, and
Below the extraction feed liquid levels.
Further, partial pressure valve is set between the gas source and the storage cylinder, is set in the air inlet pipe.
The utility model provides a kind of Solid Phase Extraction liquid storage device, has the advantages that：
1, extraction feed long-time exposed to air is avoided, and then the labile element in raw material is avoided to decompose, is dropped
The loss of low target object, improves the accuracy of experiment；
2, it can be started by controlling partial pressure valve, suspend addition extraction feed and control raw material flow rate, it is former without loading repeatedly
Stream speed is easy to control, quick；
3, structure is simple, be easy to make, production cost is low, practicability is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure：
1, liquid storage bottle, 11, bottle cap；21, gas source, 22, partial pressure valve, 23, air inlet pipe；31, outlet tube, 32, extraction connector.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described implementation
Example is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, this field
Those of ordinary skill's every other embodiment obtained without creative efforts, belongs to the utility model
The range of protection.
As shown in Figure 1, its structural relation is：Bottle cap 11 is set to 1 bottle mouth position of liquid storage bottle, is tightly connected with liquid storage bottle 1, constitutes
Closed containing cavity, cavity is interior to store extraction feed liquid；Air inlet pipe 23 and outlet tube 31 are each passed through the setting of bottle cap 11, air inlet pipe 23
It is sealed with outlet tube 31 and 11 junction of bottle cap；23 one end of air inlet pipe is connect with gas source 21, and the other end is located in liquid storage bottle 1, and
More than extraction feed liquid levels；31 one end of outlet tube is connect by extracting connector 32 with solid phase extraction column, the other end
In liquid storage bottle 1, and it is located at extraction feed liquid levels or less.
Preferably, partial pressure valve 22 is set between gas source 21 and storage cylinder 1, is set in air inlet pipe 23.
In specific extraction process, on a small quantity when charging, partial pressure valve 22 is opened, the gas in gas source 21 enters through air inlet pipe 23 to be stored up
In liquid bottle 1.Extraction feed liquid in liquid storage bottle 1 is flowed through solid phase extraction column by outlet tube 31 and is occurred under gas pressure
Extraction reaction.The charging of extraction feed liquid can be suspended by closing partial pressure valve 22, and the aperture of adjustment partial pressure valve 22 is convenient to
Realize the control of extraction feed flow rate of liquid.
In entire extraction process, extraction feed liquid does not contact before flowing out solid phase extraction column with air, avoids extracting
Raw material long-time exposed to air is taken, wherein labile element decomposition is caused.
